펌웨어 2.5/2.6의 커널모드 해킹소식이 나온지 20시간만에 펌웨어 2.5/2.6용 다운그레이더 테스트버전이 공개되었습니다.
이 다운그레이더는 닥스로더로 유명한 Dark_AleX가 개발한 것으로 아직은 검증되지 않은 테스트버전입니다.
다만, 펌웨어 2.6인 PSP에서 단 한번 테스트해본 결과 2.6에서 1.5로 다운그레이드가 되었다고 합니다.
이 다운그레이더는 테스트 버전이므로 이 프로그램을 사용하여 발생하는 불이익에 대해서는 책임지지 않는다고 합니다.
아래는 사용방법입니다. 시간이 나면 번역을 하겠습니다.
운영자주: 그동안 펌웨어 2.5/2.6용 Homebrew 개발을 포기했던 개발자들이 이번 해킹사건으로 다시 한번 불이 붙기 시작했습니다. 개발자 포럼마다 개발을 중단하였던 2.5/2.6용 에뮬레이터나 각종 프로그램들을 속속 공개되고 있습니다.
1.50 유저용 가이드 ----------------------------- 1) Copy the folders downhelper and downhelper% from the folder 1.50 HELPER folder to /PSP/GAME/ in your memstick. 2) Obtain the 1.50 update EBOOT and put it in /PSP/GAME/UPDATE in your memstick. 3) Init the downhelper program. It will dump your flash and some files from the updater eboot to the memstick. 4) After that, the program will exit. You can now delete the updater from /PSP/GAME/UPDATE 5) You'll notice that you have a new folder in the root of your memstick called "DOWNDATER". That's the folder you'll have to send to a 2.50/2.60 to let him test the downgrade. 펌웨어 2.50/2.60 유저용 가이드 ----------------------------------- 1) Copy the folder the DOWNGRADER/2.50/DOWNDATERTEST if you have 2.50 or DOWNGRADER/2.60/DOWNDATERTEST if you have 2.60 to /PSP/GAME/ in your memstick 2) Wait someone with 1.50 to pass you a folder called DOWNDATER and copy it to the root of your memstick. 3) Init GTA and the GTA Loader 4) In the GTA Loader menu, choose the downdater test. WARNING: the program won't output any display and any warnings, it will init the downgrader process inmediatelly. 5) You'll see the your memstick flashing. That means that your PSP is being flashed from the memstick. You won't see any type of output in the screen (this is for safety). When the memstick finishes of flashing, WAIT at least a minute, and then reinit your PSP by holding the power button. 6) That's all. If all went right, you'll have 1.50. If it went less good, you'll still have 2.50/2.60. If all went wrong, you'll have a broken PSP (except in the case you have the mod-chip) Remember that you have accepted that risk. Technical details ------------------ This program performs the following operations. - It loads the ipl_update.prx and lflash_fatfmt.prx from the 1.50 updater. - It performs a logical format of the flash0 partition using the function sceLflashFatfmtStartFatfmt found in the lflash_fatfmt.prx - It writes a dump of the 1.50 flash0 to the flash0. - It writes the Initial Program Loader (Ipl) using the functions sceIplUpdateClearIpl and sceIplUpdateSetIpl from the ipl_update.prx module. The ipl is embedded in that module.
